Checked the system. The blower was running on the furnace. Checked the condenser for power. There was 24 volts to the contactor but it was not pulled in. Checked the pressures. The system was off on low pressure. There as 1.8psi in the system. The customer wanted to add refrigerant to the system to get it going then they will replace it. Added 7 lb 8 oz R410a to the system. System is cooling properly at this time but does need to get replaced due to a leak.
